Why does my furnace keep shutting off?

Published on September 15, 2017

There is usually a sense of anxiety when you notice something isn’t quite right with your furnace. You’re relaxing at home and you notice your furnace is constantly kicking in and shutting off. However, before you panic, there are some things you can check when you realize your furnace seems to be shutting off more frequently than it should be.

Check the air filter in your furnace—You may think that air filters are only used to help keep the air in your house cleaner, but they also help keep your system clean. Your first step when you recognize a concern with your system should be checking your air filter to see if it should be replaced. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.

Look at your thermostat—For lots of us, we may have set our thermostats weeks ago and forgot about it, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is occurring or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be wrongly assuming your home is already up to the desired temperature.

Check out your windows for proper insulation—If your home doesn’t have the right insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to ensure they are all closed and inspect the seals around your windows for any drafts or cold air entering the home.

While you can certainly check for some of these issues yourself, if issues still occur after these checks, it might be time to call in the experts. When your furnace is consistently turning off, it can lead to unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
